Spatio-Temporal Shape Parameterization of the Human Ventricles
Acta Polytechnica Hungarica · 2015
This paper gives a solution for improving the geometric estimation of the human ventricles, by reducing their shape estimation error.The parametric description of the studied organ can be performed at arbitrary resolution during the whole visualization process.After the problem description, the paper presents each main step of the proposed shape estimation algorithm.The presented method determines not only the general shape of the ventricles, but the internal tissue direction, too.The estimation error decreases more than 10 times if the resolution is increased by 3 times.The biological parameters like gender or age also affect the estimation performance.The obtained accuracy of the method was slightly higher in the case of female hearts and for the left ventricle.Finally, concluding remarks emphasize some important features of the given approach and the future research directions.
